NEED HELP ASAP!!!!The steps below show the work of a student used to calculate the number of yards in 6,436 meters.

(1 mile = 1,609 meters)
(1 mile = 1,760 yards)

Step 1: 6,436 meters multiplied by conversion factor 1 mile over 1,609 meters equals 4 miles

Step 2: conversion factor of 1,760 yards over 1 mile divided by 4 miles equals 440 yards

Step 3: 440 yards
(1 mile = 1,609 meters)
(1 mile = 1,760 yards)

How can the error in the student's work be corrected? (1 point)

a
The 6,436 meters and the 1,609 meters in Step 1 should be switched.
b
The 1 mile and the 1,609 meters in Step 1 should be switched.
c
The conversion factor should be multiplied in Step 2 instead of being divided.
d
The conversion factor should be added in Step 2 instead of being divided.
